Rexford is located in Saratoga County and in the Central Region of the state. It was named after Edward Rexford a settler and Dolle's Amusement Park operated here from 1904-1933. Rexford is part of the Albany-Schenectady-Troy, New York metro area.

The Trolley Bridge" was built and opened July 1, 1904 by the Schenectady Rail Company and American Bridge Co. It was built upstream from the Rexford Bridge in Alplaus to give trolleys an express route to Saratoga County from Niskayuna. It was 1800' long with a high steel trestle on top of limestone piers and was the "longest trolley bridge in the world". It served as a trolley crossing to the Rexford/Luna Amusement Park where people could go for carnival rides and the roller coaster (1901-1933).

Site of Rexford Amusement Park: Rexford Flats was first settled by Edward Rexford. His great grandson, Cyrus Rexford, built the large Victorian house at Riverview Road and Route 146, now Rexford Crossings, in 1883. The Methodist Church, built in 1839, and the blacksmith shop across the road are survivors of Rexford's canal era. By 1906, a full fledged amusement park, Luna Park, existed at Rexford. It had a merry-go-round, roller coaster, airplane ride, games, refreshments and a picnic grove. An electric trolley brought people from nearby Schenectady. The park failed during the depression years, and has since vanished. Many old timers remember the park as Dolle's Park, named after the family who last owned it.

The Luna Park amusement park opened in Rexford, NY in 1906. It was known at various times as Dolle's Park, The Colonnade, and Rexford Park. The park ceased operations by the mid 1930s and was dismantled in 1935.
